BB credit configuration parameter ...

This on is on just about every version of the fabric OS. I've tried reseaching this and found very little info about it in most of the docs. I am aware about what buffer credits are and their function. Can anyone tell me more info about what this specific parameter actually does? What affect on the SAN will tweaking this have? What types of situations need this set higher or lower? Thanks.

Re: BB credit configuration parameter ...

I was hoping for a more intelligent explanation as to the use and functionality of this specific parameter. What cases should it be set higher or lower. Any side affects, etc.The documents just describe this parameter as "the number of buffers available." Duh?!
